Gates 19999 HVAC Heater Hose - Heater Outlet

Gates Molded Heater Hose for Nissan Sentra

The Gates Molded Heater Hose, part number 19999, is a factory-molded coolant hose built for tight engine compartments where a straight hose will not route correctly. It is made from EPDM and is approved for coolant, water, air, and marine applications.

Compatible with 2013-2019 Nissan Sentra heater outlet applications, this molded hose follows the OE-style shape needed for proper routing in compact HVAC and cooling system layouts. The Gates 19999 is also cross-referenced to Baldwin 19999 for the same application.

Key Features

• Factory-molded, OE-style hose shape for precise routing
• EPDM construction for coolant, water, and air service
• Small inside diameter design for tighter engine bay packaging
• 19 mm inside diameter at both ends
• 16.3 in. centerline length for application-specific fitment
• Approved for marine applications

Product Details

Gates 19999 is part of the Molded Heater Hose line, which focuses on shaped hose routing for modern vehicles with limited clearance around the engine and HVAC system. For Nissan Sentra heater outlet service, the molded profile helps maintain the intended hose path and connection geometry. This part number 19999 is a direct fit reference for 2013-2019 Nissan Sentra heater outlet use, and it supports the same type of routing found in OE-style cooling and heater circuits.

Common Problems It Can Address

• Cracked or deteriorated heater hose material
• Improper hose routing in a tight engine compartment
• Coolant leaks at a worn hose section
• Restricted fitment caused by a hose that does not match the original bend
• Service replacement for a damaged heater outlet hose on Nissan Sentra models

Installation Notes and Tips

Verify hose routing, end diameters, and centerline length before installation. Match the molded shape to the original hose path on the vehicle to avoid kinks, twist, or tension at the connections. Inspect adjoining clamps, fittings, and nearby coolant components during service so the replacement hose can seat correctly.

Quality Assurance

Gates is known for OE-style hose engineering and application-specific molded designs. The Molded Heater Hose line is built to support accurate fitment in compact engine compartments and consistent service in coolant-related applications.
